    2004 Yukon - Rumbling at ~50mph - Please help!!

    If it's shuddering at/around 40mph then it could very well be converter....Was the converter replaced when the transmission was rebuilt. Also, describe to me what you're referring to as a 'sticky' 1-2 shift - no clue what that means...Is it late and harsh or early/overly soft...Does the trans...

    2004 Yukon - Rumbling at ~50mph - Please help!!

    Not sure why you'd think a transmission rebuilt by a competent shop would be any worse than a 'full replacement', especially considering the amount of hack reman companies out there. Insofar as the problem itself, how long has this been happening? Was it occurring before the transmission was...

    Transmission Woes Continue!

    Like @rockola1971 said, black dust is a bad sign, if in quantity at the bottom of the pan. You're also going in and out of limp mode (3rd and reverse only). Did you continuity-test all the solenoids when the pan was off? Visual inspections are fine but only tell half the story... You need to...

    4l80e direct clutch feeplay

    Appreciate the views, man...So did you arrive at your clutch clearances in the fwd and direct drum following the process I show in the video or no?

    4l80e direct clutch feeplay

    Watch this video (re-watch if you've already watched) - skip to 1:20:00 and see how I measure my direct clutch clearance....If your process is not identical in every way to mine then re-do the clearance check mirroring the steps I show here:

    4l80e direct clutch feeplay

    Hopefully you havent done anything like sand your pressure plate. Please answer my question - list and describe how you are measuring your clurch clearance. I suspect you're not doing it correctly but want to confirm based on what you tell me. I wont answer any other questions unless you...

    2017 Tahoe Trans rebuild advice?

    That bill is typical of these transmissions; labor rates here in Vegas are running between $175-225 per hour. My cost to rebuild 6L transmissions is approaching 5k; parts prices keep going up in ways I've never seen before until post-Covid. At this point, you're pretty much stuck with...

    What the hell is this????

    I dont do t cases as they are much more cost effective as good-used replacements instead of having the pre-existing one rebuilt That said, I suspect @B-train nailed it...

    4L60e issues after rebuild

    You're welcome, hopefully you can salvage it without having to refund the entire job.

    What do I need to reset codes?

    You simply need a scan tool capable of clearing the code...I would think most basic, low-buck scanners can clear an evap code since it's an emissions related DTC.

    4L60e issues after rebuild

    Why are you reusing things that should be tossed? All electronic/electrical parts should be put in the trash and replaced with AC Delco, Rostra, Delphi or Borg Warner components. Its begging for a comeback when that stuff is reused (esp 2006+ 4L60Es with TSS). Same with the converter, which is...

    4l80e direct clutch feeplay

    The dir drum doesnt take a bushing. How exactly are you measuring your clearance in those two drums? List the steps you're taking...want to make sure you're doing it correctly.

    No clue what that is.

    4l80e direct clutch feeplay

    Hi Blackbeard, Pull the piston out and check the lip sealing surfaces on your piston (im assuming you have a new bonded piston - if not, obtain one)...Also make sure the sealing surface in the drum isn't compromised in any way or the inner diameter of the direct drum doesn't have sealing ring...

    What do I need to reset codes?

    Have you fixed this yet? If not, wonder if it's simply your gas cap needing to be replaced. If that's it, should clear on its own once a new cap is installed.

    High RPM while Light Towing & Upgrade Transmission?

    Keeping the Yukon? Segment swap to a 4L80E and be done. Easy button if towing frequently and heavier loads up and down grades in mountainous areas.

    P0700 code on 2019 Tahoe

    Not sure if you've figured this out already but if not, take the vehicle for a drive with a two way scan tool plugged in and live transmission and torque converter data displayed. You want to monitor things like tcc slip speeds at 70% or higher tcc duty cycle (should be no more than 10 rpm or...

    2017 Tahoe Trans rebuild advice?

    Yep, a good tune should compliment the mechanical overhaul when it comes to these and other clutch-to-clutch transmisssions

    2017 Tahoe Trans rebuild advice?

    See my 6L80 Information Thread for upgrades (link in my sig) - I made that thread specifically for DYIers and other intereted parties to simplify and bring clarity to dealing with these transmissions. Upgraded TC, Sonnax Zip kit (or Transgo repro kit), Sonnax billet 4-5-6 clutch hub, piston...

    Severe problems after trans fluid change

    Interesting - glad it was something simple!

    Severe problems after trans fluid change

    Yep, agree. Take to a reputable shop, one not connected to that guy. Both low fluid and filter not seated (or cracked filter, because he broke it lol). There's a fill procedure that has to be followed for those transmissions, maybe he didnt follow it.

    Severe problems after trans fluid change

    My thoughts are that maybe he screwed up and is now telling you to fix his mistake. Get the vehicle to operating temp and check fluie level. While doing so, smell the fluid on the dipstick to see if it smells burnt at all. If you have a scan tool, plug in to grab any codes that may be stored...

    Please quote my post if you'd like me to respond as I don't get notifications... Have you informed him of what's been happening after the service? If so, what did he say?

    Stator shaft torx screws

    Check for old thread locker on the threads and then check the threads in the stator support to see if they're partially stripped out (sometimes happens when stator bolts are removed) - assuming you haven't already done this...Otherwise, perhaps put a little WD40 on the threads and attempt to...
